Modular hot-pressing shaping mechanism

Abstract

The invention discloses a modular hot-pressing shaping mechanism, which comprises a fixed frame, wherein a lifting channel is formed in the vertical direction of the fixed frame; a hot-pressing upperdie structure is located above the lifting channel; a hot-pressing lower die structure comprises a hot-pressing lower die assembly, a lower die mounting base plate and a lifting oil cylinder; the hot-pressing lower die assembly is located on the lower portion of the lifting channel; and the lifting oil cylinder drives the hot-pressing lower die assembly to ascend or descend in the vertical direction, so that die assembly or die opening is achieved between the lower die core and the upper die core. Modular manufacturing and mounting can be achieved, the difficulty of machining, manufacturing, mounting, debugging and maintaining can be effectively lowered, and the comprehensive cost of manufacturing and using can be effectively lowered. As a complete and independent hot-pressing shaping working module with excellent performance, the hot-pressing shaping working module not only can automatically, integrally and independently complete the hot-pressing shaping process of pulp molding, but also can be flexibly integrated into various sets of large multi-station pulp molding production equipment according to actual requirements by serially and parallelly combining a plurality of modular units.

Description

technical field [0001] The invention relates to the technical field of hot-press shaping, in particular to a modular hot-press shaping mechanism. Background technique [0002] At present, pulp molding products are green and environmentally friendly products made of plant fibers or waste paper products that can be completely naturally degraded and recycled. The production process of pulp molding consists of pulping, adsorption molding, wet embryo transfer, The process of hot pressing and shaping is completed; it is widely used in the fields of food and drug storage, electrical packaging, planting and seedling cultivation, medical utensils, handicraft base blanks, and fragile liner packaging. [0003] In the prior art, a certain amount of hot-press drying time is necessary for the processing of hot-press shaped products, and hot-press shaped products take the longest time in the production process of pulp molded products. In the actual production process, most of the processe...

Problems solved by technology

This kind of hot-pressing upper die and lower die-clamping structure driven by the gas-hydraulic pressurized cylinder has the disadvantages of troublesome processing and manufacturing, difficulty in ensuring high-precision matching, and inconvenient maintenance and repair.

When the gas-liquid pressurized cylinder drives the mold to move up and down, it is essentially a cylinder. Due to the compressibility of compressed air, the movement rigidity of the cylinder is poor. When the hot-pressed upper mold moves up and down, it will appear due to the change of resistance. Instability and shocks such as crawling or jumping

Since the moving mold is placed on the top, after the gas-hydraulic pressurized cylinder is used for a long time, oil leakage will inevitably occur due to the wear of the seal, which may cause direct contamination of the hot-pressing mold and the product.

In addition, in the case of unexpected power failure and long-term shutdown, there is a potential safety hazard that the upper meme will fall due to its own weight and damage the mold. Additional costs must be added to install safety auxiliary facilities
